HomeMy WebLinkAbout418 LINDEN ST - SPECIAL INSPECTIONS - 6/28/2011Analytical results for these materials indicate that there is no asbestos present in the plaster, and only trace amounts (<1%) in the vermiculite insulation. Currently, the State of Colorado and the USEPA define building components that contain more than 1% asbestos to be ACM. By definition, therefore, the vermiculite is not considered to be ACM for the purposes of demolition and removal. However, in order to comply with OSHA worker protection requirements, the vermiculite should be wetted during removal. Wetting the material is necessary to prevent airborne vermiculite that could be ingested by demolition workers (other engineering controls to prevent the ingestion of airborne vermiculite can be used, however, wetting is typically the most cost effective and expedient way to limit worker exposure). The demolition contractor should be provided with this information prior to removal and should keep a record that this protocol was followed. LTE has attached a copy of the analytical results for Aggregate Industries records. Please contact myself or Susan Borden at 303-963-5493 if you have further questions regarding the removal of the vermiculite. Kay Vollmayer, P.E.

The rail car and shed were determined to not have any suspect ACM present and therefore no samples were taken from these areas. Mr. Fodor determined that the ACM identified in the batch plant operations room (black mastic that adhered the wood paneling to the drywall) and the drivers room (brown mastic on the ceiling tiles) had been removed. However, as a result of construction activities Mr. Fodor was able to identify the following suspect ACM, not previously identified: plaster on outside of cinder block buildings and vermiculite insulation inside cinder blocks on all cinderblock buildings. Mr. Fodor sampled these materials and submitted the samples to Reservoir Environmental, Inc. in Denver, Colorado for analysis. r INSPECTIONBUILDING frr 3i �r tA- I 1'roject Number: CABI Number: frirry .��..,r.^F L ��x �r�,,, �r4�F ,xj.'vjj L �.y, .'•,Y .,fir li �',;,R }I, ���cy - 1rS /nAAyy� t'S, 1 1 'l y ...Y 'F' aS_ �. �eXn' ^.. i'�!`� ....r¢� 11t,'.ky-Y1` Y�'T�Wyy�Ci ... s•i•..,Fvs 4.F Y� 1"tf'S' 'r•. t� a .. ,: "1 rryy `Y � 1 ' •I 5.

'600 West 601h Avenue Arvada, Colorado 80003 T 303.433.9788/F 303.433.1432 LT Environmental, Inc. (LTE) was retained by Aggregate Industries US (Aggregate Industries) to conduct a survey -of suspect asbestos containing,material '(ACM). The ACM survey. was conducted at the non -operational Linden Ready Mix concrete batch plant located at 418 Linden Street, Fort Collins, Colorado (Site), on May 27, 2011. LTE understands the batch plant. is .scheduled for demolition pending approval by the City of Fort Collins. This report summarizes the independent conclusions representing" LTE's professional judgment based on information and data available to LTE during the course of the survey. Factual information regarding planned demolition activities at the Site provided by Aggregate Industries has been assumed to be correct and complete. Additionally, the conclusions presented'herein are based on the conditions that existed and samples analyzed on the date of the survey. _ This report is exclusively for the use and benefit of Aggregate Industries and is not for the use or. benefit of any person or entity, nor -may any other person or entity rely upon this report without the express written consent of LTE. ACM SURVEY ACTIVITIES The survey was conducted by Mr. Daniel R. Moir, Certified Asbestos Building Inspector (State of Colorado Certification No.. 13237), utilizing methods and procedures consistent with good commercial and customary practice designed to conform to acceptable industry standards. The survey was solely intended to assess the potential asbestos content of those buildings planned -for demolition (Attachment 1 Photographic Log) including: • A sheet -metal batch plant with a boiler and a hopper with conveyor belts (Photograph 1); • A wood -framed batch plant operations room (Photograph 2); • A cinder block and wood -framed drivers room (Photograph 3) • A cinder block mechanical room (Photograph 4); and Hess, D Page 2 i I A rail car with an associated wood -framed shed (Photograph 5). Below are descriptions of the fifteen samples of suspect ACMs collected from materials for the suspect ACM survey The Photographic Log is included as Attachment 1. and the Building Inspection Forms are included as Attachment 2. Three drywall samples (DWO1, DW02, and DW03) from behind the wood, paneling on three walls of .the batch plant operations room (Photograph 6) including the paper covering. Drywall sample DW03 included a black mastic that adhered the wood paneling to the drywall; Three ceiling tile samples (CTO1, CT02, and CT03) from the ceiling of the batch plant operations room (Photograph 7) including white and brown mastic on the backing of the tiles; • Three drywall samples (DW04, DW05, and DW06) from the ceiling of the drivers room (Photograph 8). The visible drywall did not contain mud or tape; • Three ceiling tile samples (CT04, CT05, and CT06) from the ceiling of the drivers room (Photograph 8) including.brown mastic on the back of the tiles. The tiles.are adhered to the drywall on the ceiling; and • .Three gasket seal samples (GS01, GS02, and GS03) from the boiler in the mechanical room (Photograph 9). The gasket seal is a rope -like -seal around a steel plate on the northwest side of the boiler. The rail car and shed were inaccessible at the time of the suspect ACM survey. As a result, the CABI could -not sample suspect materials to confine the presence or absence of asbestos in the rail car and shed. The CABI observed asphalt shingles on the roof of -the -batch plant, the batch plant operations room, and the drivers room at the Site. The roofing material appears to be in good to poor condition. LTE did not collect samples of the asphalt shingles as it is an industry practice to assume the shingles contain asbestos. Two boilers were identified at the Site. One boiler was observed in the mechanical room (Photograph 10, Attachment 1) and one boiler was observed in the batch plant (Photograph 11, Attachment 1). The CABI was not able to open either boiler and assess whether the boilers were lined with ACM or not. As a result, no samples of insulating materials from .the boilers were collected. Prior to sampling, the accessibility, location, and friability of the sample locations were recorded. This information was used to assess the potential hazard of the ACM, if found to be present, and to prioritize response action recommendations. Each suspect ACM sample was obtained after wetting the area to be sampled. A small section of the suspect material from the sample location was carved using a clean stainless steel knife and then placed into a sealable bag. The bags were sealed, labeled, and. transported to the -analytical laboratory for testing using polarized light Hess, D Page 3 microscopy (PLM). Suspect ACM with duplicate samples were analyzed on a positive -stop basis, which ceased testing of remaining duplicate samples with the first detection of asbestos. The samples were transported to FRS Geotech, Inc., an independent laboratory in Denver, Colorado, which is accredited by the American Industrial Hygiene Association (AIHA) and successfully participates in the National Voluntary Laboratory Accreditation Program (NVLAP). ACM SURVEY RESULTS The United States Environmental Protection Agency (EPA) defines ACM as those materials that contain greater than 1 percent (%) asbestos. Friable materials are defined as those materials that can be crumbled or reduced to powder by hand pressure. The latest revision of the National Emission Standards for Hazardous Air Pollutants (NESHAP) stipulates that any friable material identified as containing asbestos in any concentration must be considered asbestos -containing. The laboratory analytical results indicate the black mastic that adheres the wood paneling tothe drywall in the batch *plant operations room contains asbestosat a concentration of 4%. In addition, the laboratory analytical results indicate the brown mastic on the ceiling tiles in the drivers room contains asbestos at a concentration of 3%. The laboratory analytical report is included as Attachment 3. CONCLUSIONS The black mastic that adheres the wood paneling to the drywall in the batch plant operations room is considered an ACBM. The mastic is on the backing of the wood paneling, which covers approximately 512.square feet (W) of wall space. ..The brown mastic on the ceiling tiles- in the drivers- room is considered an asbestos containing building material (ACBM). The mastic is on the back of the, ceiling tiles, which covers approximately 270.ft2 . The asphalt shingles on the roofs of the batch .plant, the batch plant operations room, and the drivers room at the Site are presumed contain asbestos. The. roofing material appears to be in good to poor condition. Two boilers were identified at the Site. One boiler was observed in the mechanical room and one boiler was observed in the batch plant. Boilers tend to be insulated with asbestos. As a result, the two boilers.are presumed to contain ACM. The rail. car and shed were inaccessible and were not -inspected during the suspect ACM sampling survey. The rail car and shed have the potential to contain ACM. Hess, D Page 4 RECOiVIiVIENDATION Prior to demolition of the buildings located at the Site, LTE recommends that all ACMs be removed in accordance with state and federal regulations. In addition, LTE recommends sampling the rail car and shed prior to demolition to confirm the presence or absence of ACM: LTE appreciates the opportunity to have provided this survey.

Bulk Sample Analytical Procedures Bulk samples of construction materials are analyzed according to the Methodfor the Determination of Asbestos in Bulk ButldingMafertals (EPA/600/R-93/116) which the EPA recommends as the "preferred substitute" to the old Interim Method. In areas where t ertew" Method is silent, FRS follows the "old" Interim Method and/or specific rulings issued by the various regulatory agencies. Each separable layer or portion of the sample is individually analyzed and reported, along with each layer's volume percent as a part of the total sample. Additionally, an arithmetic composite for the total sample, as received by the lab, is reported for layered' samples. Information on the nature and quantity of materials at the sampling site, which is unavailable to FRS, must be used by the' client to determine whether or notthis arithmetic composite of the sample is representative of the materials, as they exist in place. This same information must be used by the client to determine whether or not any layered material, as it exists in place, should be treated as several different materials or as a composite material. Each sample layer is prepared and analyzed in refractive index oils that are certified by the manufacturer, Cargille ' Laboratories. Refractive indices are measured by the Dispersion Staining, Becke Line, or Oblique Illumination methods, according to which method is most applicable to the sample material. Asbestos content is reported as a percent of the sample, and is a visual estimation based upon gross sample examination and comparisons with published calibration charts during PLM analysis. Sample Ashine Ashing is a preparatory procedure carried out to eliminate many interferents and asbestos "look-alikes." A portion of the sample is placed in a fiance at 500 degrees Celsius for between I and 4 hours; the actual time varies according to sample type. The amount of asbestos present in the original sample is calculated, based upon the weight loss due to aching. If the sample had a 50% weight loss, and the visual estimation of asbestos present was 20%, the amount of asbestos reported would be 10%. All ashed samples are so noted on the Final Report. Non-Asbestiform Amoblbole Minerals Particles of NON-ASBESTIIrORM anthophyllite, tremolite; and actinolite with length to width ratios equal to or exceeding 3:1 and overall lengths greater than 5 microns are occasionally detected in some bulk samples. While such particles do meet the "old" legal definition of fibers, they do not meet the classical definition of asbestos because they do not occur as bundles of parallel fibers (often exhibiting splayed ends), matted masses of individual fibers, or long, flexible, and/or curved individual fibers. The majoiity of mineral fibers in a sample must display these characteristics as well as exhibit a length to width ratio of at least 20:1 for the mineral to be designated "asbestos." These guidelines are specified in the "New" Method: EPA/600/R-93/116. Our Final Report refers to:non-asbestiform anthophyllite; tremolite,-and actinolite as either "Non-asbest. trem./actin.", or'Non-asbest. anthophyl.", whichever is appropriate. A /OC Procedures and the Uncertainty of Analyses All laboratory tests are performed according to rigid QA/QC guidelines, and analytical results are traceable to known reference standards and procedures. In addition to the legal requirement that 10% of all samples received be re -analyzed, FRS Geotech re -analyzes all samples for which a trace to 3% asbestos is reported. The New Method (EPA/600/R-93/116) contains the following Suggested Acceptable Error Table for PLM analyses with quantification by visual estimate over 100 fields.of view: Areal PercenhAsbestos Acceptable Range of Asbestos Reported 1% >0%to 3% 5% 1%to 9% 10% 5% to 15% 20% (or more) plus or minus 10% June:7, 2011 City of Fort Collins Planning, Development &,Transportation 28.1 North `College Ave, !
